obviously everything cosworth is the nuts, are the bottom end bearings any better then ACL race?

 

I have been looking into this aswell, on paper I've read the ACL bearings are rated to 800bhp and the Cosworth's to 1000bhp.

But I think some input from an engine builder who has used both would be best

 

Many specialists defo supply and fit ACL Race Series mains and bigs, as a matter of course.

At the end of the day either are no doubt great.

Just depends if there's a significant price difference(?) - will invariably be the clincher... unless you intend to go for >/= 801bhp

 

but im sure the standard bearings on my car aint rated to 280bhp but they still spin lol

 

We supply and fit Cosworth as a matter of course on every engine we build. If they are out of stock, we fit ACL race. I don't think there's anything in it.
